Travelgalsue: I've thought about those space saver bags - did it make your suitcase any heavier?

My must have is a bit different. I like to buy a perfumed body spray or cologne somewhere on my trip and use it. Then months after I return and I use that scent, it brings me right back to my vacation. I have one scent I bought in Vegas 5 years ago and every time I use it (it's a Victoria's Secret cologne) it still reminds me of that vacation.
